在通信系统中,由于网络可运载的业务量是有限的,随着输入业务量增加会使得网络出现聚集现象和通过量大大下降,并引起时延大大升,从而导致网络无法正常运行,因此要求采用必要的流量和拥塞控制。 In the communication system, since the amount of traffic that can be carried by the network is limited, as the amount of input traffic increases, the aggregation and throughput of the network will be greatly reduced and the delay will greatly increase, which will result in the network being unable to operate normally. Therefore, Use the necessary traffic and congestion control.
